So, Kindle Touch update 5.3.7 has just come out.
Unlike all previous updates, which were all differential updates, this one contains the full system. This means that all modifications are lost during the upgrade
, INCLUDING THE JAILBREAK (unless you already had the jailbreak bridge installed).
There are two solutions, depending on your situation.
1. If you are still on an earlier Firmware version
, install the jailbreak bridge from NiLuJe's Kindle Touch jailbreak
. It's the file named update_jailbreak_bridge_*_install.bin inside the jailbreak zip that you'll want to install.
This will (try to) ensure that the jailbreak survives future firmware updates.
2. If you are already on FW 5.3.7
and do not have the jailbreak installed (symptom: Error 007 when trying to install a custom update.bin), then use Kubrick
. DO NOT let it overwrite the main partition when asked - otherwise you'll end up with FW 5.1.2. Instead, skip flashing the main partition, and only select to install the jailbreak.
It's also a good idea to install the jailbreak bridge (see item 1. above).
